Re: [Freesurfer] GRF correction

We do not have a GRF algorithm (at least one that I trust yet). Alternatively, you can perform monte carlo or permutation simulation with mri_glmfit, and this gives the same (or similar) information. > You mean for FDR estimation? > > 2008/6/23 Pedro Paulo de Magalhães Oliveira Junior <[EMAIL PR

Re: [Freesurfer] Talairach_avi and eTIV, version 3.0.5 vs 4.0.5

Hello All, We are interested in the ranges of eTIV values found by other Freesurfer users.  As noted below, one research group reports a mean ICV of about 1560 cc for adults ranging from 20-90 years old.  Our sample (n=40) including males and females (51 to 83 years old) has a mean eTIV of 1

[Freesurfer] GRF correction

Hi, I understand that there are tools under development implementing Gaussian Random Field correction for multiple comparisons. If there is a usable version available (and a brief description of how to use it), I'd like to try it out. Thanks in advance, Cate Hartley _

[Freesurfer] white matter volume - version 3.0.5 vs 4.0.5

Dear Freesurfers, Is it acceptable to use the program "mris_wm_volume" from version 4.0.5 (Cent OS, x86_64) to calculate total white matter volume from data processed with version 3.0.5? Would I need to subtract any subcortical volumes such as ventricles, basal ganglia, etc, from the output o

Re: [Freesurfer] Talairach_avi and eTIV, version 3.0.5 vs 4.0.5

Hi yes, the FS ICVs mostly seem to work :-) I still think one should watch out for outliers. We had a sample of 28 kids aged 8-13 yrs, and the ICVs were quite a bit off and useless for two of those, so I would check all carefully especially if you have a group that may have smaller than normal ad

[Freesurfer] inorm-sess error

Hi, I'm trying to get around the problems from my previous post: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg07669.html I am now trying to use mri_convert to convert from nifti to bshort using the following command: mri_convert -i rfkoch-0021-00144-000144-00.nii -it nii -o fs

Re: [Freesurfer] Talairach_avi and eTIV, version 3.0.5 vs 4.0.5

Hi, for those interested: we have correlated FS's ICV estimates and estimates from a procedure developed by Anders Dale (a deformable template procedure, similar to the “Shrink Wrapping” procedure previously described by Dale and colleagues (Dale et al, 1999; Dale and Sereno, 1993)). Mean ICV from

[Freesurfer] Reanalyzing some OASIS cases

Hi, I would like to rerun recon-all (from the latest freesurfer) on a few cases from OASIS brains study, to get control values for my patient group. Since my computational options are rather limitted, I would like to avoid running redundant steps, which would anyway give me the same results, or
